,This invention relates to the broad class of railway equipment and tools and has more specific reference to a mechanical device especially designed for dislodging and extractj 5 ing damaged rail ties to make way for replacement ties.

Briefly stated, the desired results are accomplished through the provision of a structure including a novel quick applicable rail clamp and tool mounting, together with a tongue-like tool and operating means therefor properly assembled and coordinated to withdraw the tie from beneath the rail.

One feature of novelty is predicated upon the unique tool sustaining device and the simplified rail clamping means for maintaining said device in position on the tie and rail while the tool is actuat-edfor dislodging and extracting ties.

A further feature is predicated upon the provision of a foot depressedaccessory constituting a part of the clamping device, which accessory aids materially in maintaining the mounting and clamp in rigid position while operating the tool.

A still further feature is based on the especially designed tongue like tool and simple lever operating means therefor permitting an intermittent progressive gripping action of the tool on the tie to withdraw the tie in a step by step manner.

Other features and advantages will become more readily apparent from the following description and drawings.

In the accompanying illustrative drawii wherein like numerals are employed to des g nate corresponding parts throughout the views;

mately on the p ane of the line 6-6 of Figure 2.

Figure 7 is a fragmentary detail view of one of the parts of the tool.

Figure 8 is a fragmentary perspective view of a lever mounting and thrust bar.

Figure 9 is a fragmentary perspective view of the foot depressed end of the rail flange engaging member.

In Figure 1 of the drawings the conventional rails are distinguished by the numerals 10 and 11 and the cross tie which is adapted to be removed is denoted. by the numeral 12. In order to remove the tie it of course necessary to extract the usual retaining spikes (not shown). T he tool mounting comprises a base plate 13 which rests upon the top of the tie and which is provided at opposite ends with slotted extensions 14. The numerals 15 mere- 1y designate bearing brackets. Secured by an attaching flange 16 to the intermediate portion of the base plate 13 is a tool supporting bar or arm 17 which extends at right angles from the rails outwardly beyond the adjacent end of the tie. This terminates in a forked end 18 to which the tool operating lever 19 is pivotally attached.

The tool is distinguished generally by the numeral and is of tongue-like construction. It comprises a pair of companion duplicate jaws 21 having downbent intermediate portions 22 carrying horizontal inturned extensions 23 provided with a pointed grip 2% adapted to be embedded in opposite sides of the tie shown. The jaws are pivotally connected together as indicated at 25 and at this point of connection I provide interacting cam slots 25 in which the pivot pin operates.

I next call attention to a tie strip 26 having its opposite ends pivotally connected as at 27 to the intermediate portions of the aws to provide the requisite fulcrum mounting for said jaws. At its center this strip is provided with an extension 28 having a slot 29 and provided with a pin 30 on which the return spring 31 (see Figure 1) is attached; the opposite end of the spring is attached to the depending end portion 32 of the aforesaid lever supporting arm or bar 17 Also as shown in Figure 4; the numeral 33 designates a reciprocatory operating link having a bolted head 34 at one end through which the lower end of the lever 19 is pivotally connected as shown in Figure 1. This link carries the pivotal operating bolt 25 which operates in the cam slot of the jaws opening and closing the jaws in an obvious manner. The inner offset cut 35 of the link has a guide pin 36 extending into the guide slot 29 as shown in Figure 4.

' I next call attention to the clamping members 37 which as seen in Figure 2 comprise metal straps of appropriate portion having hooked ends 38 to engage over the base flange of the rail on opposite sides of the tie. These straps are adjustably bolted as at 39 to the slotted extension 14 of the base plate 13. i The numeral 40 designates a pressure crank which is mounted in the aforesaid bearing 15 as seen in Figure 2 in a position to swing down and press firmly against the remaining flange of the rail. One end of this crank is formed with an operating arm 11 which is seen in Figure 9 as a laterally bent portion 42 provided with a foot piece 43 againstwhich the opera tors foot is placed in order to force the crank 40 down against the rail. Hence the mounting comprises a plate 13 to rest on the tie, adjusting hooked clamping'straps 37 and the foot depressed crank 40, together with the horizontal supporting rod 17 on which the tool operating lever is pivotally mounted. It is evident that by grasping the lever and working it back and forth the jaws of the tongue take hold of the tie and extract in a step by step manner. Hence by a gradual intermittent gripping and pulling action the tongue serves to withdraw the tie from the road bed and from beneath the rail so that it may be replaced with a new tie.

It is thought that the description taken in connection with the drawings will enable a clear understanding of the invention tobe had. Therefore, a more lengthy description is thought unnecessary.

, \Vhile the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.

Having thus described my invention, what I claim as new is:

1. In a structure of the class dcscribed, in

combination, a rail, a tie located beneath the rail, a supporting plate resting on the protruding end of the tie, adjustable clamping members connected with said plate and adapted for releasable connection with a base flange of the rail, additional foot, actuated clamping means carried by said plate cooperable with the remaining flange of the rail, an arm attached to and extending out from the intermediate portion of the plate, a tie engaging and withdrawing tool, a lever pivotally mounted on the outer end of said arm having operating connection with said tool.

2. In a structure of the class described, a supporting plate adapted to rest on the tie, said plate being provided at opposite ends with a slotted extension, a pair of clamping straps adjustably connected with said slotted extensions and having their opposite ends formed with hooks engageable over the base flange of the adjacent rail, bearing brackets carried by said plate, a crank rockably mounted in said bearing brackets and swingable in a path to bear down on the remaining flange of the rail, an operating arm for the crank including a foot piece adapted to be held down by the foot of the attendant, a pair of tongues cngageable with the tie, and mechanical operating means therefor including a lever supported from said plate through the intermediacy of an arm secured to the plate.

3. In a tie extracting device of the class described, a pair of tongues comprising a pair of complemental jaws having laterally directed downwardly offset tie engaging end portions, a tie bar through which the intermediate portions of the jaws are pivotally connected, an operating link having pin and slot connection with the operating ends of said jaws, a tie engaging plate, clamping means therefor, an arm attached to said plate, a lever pivotally mounted on said arm and pivotallyconnected with said operating link.

4. In a structure of the class described, a plate adapted to rest on the tie, clamping means for said plate, a supporting arm attached to and extending horizontally from the intermediate portion of the plate, a tool comprising a pair of tongues including complemental jaws fashioned at their free end for releasable engagement with opposed sides of the tie, a connecting tie bar pivotally connected at its opposite ends to the intermediate portion of said j awsto provide the requisite fulcrnm action, the intermediate portion of said tie bar being formed with a guide slot, an operating link having a guide pin operating in said slot, an operating connection between the intermediate portion of the link and the adjacent end of the jaws, a lever pivotally mounted on the aforesaid arm and pivotally connected to said link for op erating the link.

In testimony whereof I aflix my signature.
